Extracting streams from AFF4 volumes	true	5

Analysis tools which already support AFF4 will be able to use the AFF4 image directly, but sometimes you may come across a tool which does not. In this case you will want to extract the RAW streams out of the AFF4 volume.

To extract streams from an AFF4 volume we use the -e flag.

Extract streams by using wild cards

  WinPmem.exe -e '*/kallsyms' --export_dir /tmp/export/ /tmp/test.aff4

By default export directory is the current directory. The imager will create a directory structure under the export directory which contains all the matched files.

Extract streams from stdin

  WinPmem.exe -l test.aff4 | grep exe | \
       WinPmem.exe -e @ --export_dir export/ test.aff4

In the above example, we list the streams in the volume, then grep only the executable files, and extract them into the export directory.
